FLASH-HOLDER.

To all whom t may concern:

Be it known that I, JULIUs JOHN MOJON- Nmn, a citizen of the UnitedStates, residing at Oak Park, in the county of CookA and State ofIllinois, have invented certain new and useful Improvements inFlask-Holders,

of which the following is a specification.

In the `co-pending application Serial No. 20,633, filed April 12, 1915,is described an apparatus and method of testing milk, in connection withwhich is illustrated and dei scribed an extraction flask. In carryingout the method described in this application, it is necessary to firstshake the flask and 'afterward centrifuge it, or, in other words,subject the flask and its contents to the action of centrifugal force,in order to sharpl separate, -one from the other, the immisci le liquidswithin the iask.l

The present invention is designed as a holder for a plurality of theflasks during both the'shaking and centrifuging steps of the methoddescribed in the said co-pending application supra, thus making itpossible to not only simultaneously carry out the process with a numberof specimens in lieu of one but to also eliminate all undue handling ofthe iasks.

With the above and other objects in view, as will be apparent, thisinventionconsists in the construction, combination and arrangement ofparts all as hereinafter more fully` described, vclaimed andvillustrated in the accompanying drawings, wherein Figure 1 is a frontelevation of a holder constructed in accordance with the presentinvention, illustrating several {iasks therein;

Fig 2 is an end elevation thereof;

Fig. 3 is a vertical section taken along line 3 3 of Fig. 1, toillustrate the details of construction of one of the iask-receivingl 4Specication of Letters Patent. P-tQmtgQd Jun@ im, 1913, Application medmay 2o, 191e. serial No. 98,759. l I

sockets 15.' These pockets or sockets 15 are each to receive the lowerchamber or end 11 ofan extraction flask F, the capacity and size of eachholder being determined by the number of sockets or pockets. Theformatlon of the base 14 and the arrangement of the sockets or pockets15 therein is such that the latter are independent one from the other,

and if desired extend entirely through the former. A plate 16, of metalor other adaptable material, forms the bottoms for the sockets orpockets 15, as it is of the same di-4 mensions as the' base 14 and issecured to the under side thereof by a number of screws 17 piercing theplate 16 and threaded into the base 14. A. pad 18 of shock-absorbingmaterial, such as rubber, is placed in the bottom of each pocketorsocket 15 to protect the iiash F to be located therein, from damage.

For retaining the flasks F in their'respective sockets or pockets 15, acover or lid 19 is hinged to oneI longitudinal side of the base 14 andis of a width equal to approximately one-half of the width of said base.This cover or retaining member 19 is hinged to swing to a position whereit will rest flush upon the upper face of the base 14, when in itsoperative 'posi-tion, and to swing away from the base when it is desiredto release the flasks (see dotted line position in Fig. 3).

The free edge of the cover or retaining member 19 is provided with theapproximately semi-circular recesses 20, one recess corresponding to andcoperatin with each pocket or socket 15 for embracmg the upper portionof the lower chamber-11 of a flask F within the pocket. As the recesses20 are spaced one from the other, a projection or tongue 21 is createdbetween each pair of ladjoining recesses and at the ends of the 19 to aposition where it rests flush upon the .base 14 and grasping both thebase and the cover, the holder andthe flasks therein may be shaken, theflasks F being held in place by the cover. After this shaking, theholder with all of its asks F may-be placed in a centrifuge,V the actionof the centrifugal force being sufficient to maintain the flasks intheir respective sockets or pockets 15 andthe cover or lid 19 in itsoperative position. When the centrifuging is complete, the contents ofthe upper chambers 10 of the asks F may be Withdrawn Without removingthem from the holder. rI`hus it will be seen that by the use of thepresent holder, of the size illustrated, thoughcf course the same may bemade to accommodate a greater or lesser number of flasks, four tests maybe conducted simultaneously, Without any chance of confusing orinterchange of samples.

j Compared to the depth of each socket or pocket 15, the vheight of theflasks F' would cause them to be top heavy unless some means wereprovided to support .the project-p ing portions of the asks and also toprevent them from turning in the sockets, thereby maintaining thefaucets or stop cocks 13 in fixed correlative positions. To accomplishthis, la wire support is provided for each socket or pocket 15 andcomprises a single strand of Wire bent annularly upon itself to createthe loop 22, through which passes the upper chamber 10 of thecooperating fiask F. The ends of the wire are bent Aat right angles `tothe loop 22 to form the spaced, parallel uprights 23, which support theloop 22 in a superposed position parallel to the base 14 and inregistration with the cooperating socket or pocket 15. At their terjminals, the uprights 23 are embedded in the base 14 whereby they arepermanently held fixed in any suitable manner, such as by riveting. Inpractice, it is desirable to keep all of the loops 22 within the conneslof the vertical planes of the ends of the base 14, so that no portionsthereof project beyond the base. To this end, the uprights 23 of themedial supports are embedded inthe base 14 equidistantly upon each sideof one end of the diameter of the adjoining socket or pocket 15, atright angles to the longitudinal side of the said base; while theuprights 23 of the end supports are both at one side of such diameter,so that the loops of these supports are positioned inwardly toward andin close proximity tothe `loops of the next adjacent supports. Toprevent damage to messe? the flasks F and the stop cocksor faucets 13thereof, the loops 22and the uprights 23 are covered with the rubber orother resilient tubing 24, which contacts directly with the flasks andtheir faucets or stop cocks.

In se,the flasks F are .placed in the sockets or pockets 15 and are heldtherein by the cover or retaining member 19, in the manner heretoforedescribed. When so located, the upper chambers 10 of the Vflasks rest inthe loops 22,while thesto'p cocks or faucets 13 thereof project throughthe'spaces between uprights 23 and terminate beyond the plane of thelongitudinal edge of the base 14. By having the supports eachconstructed of a single strand ofy wire, it is possible to place a flaskWithin the holder by inserting it through the loop 22 with the faucet orstop cock 13 thereof alined with the space between the uprights 23; andvreversely, the flasks may be similarly removed. After the iasksF havebeen filled with the necessary samples, ingredients, etc., and

placed within the holder, all of the dasks in said holder may be shakenand centrifuged, and the faucets or stop cocks 13 opened to allowthecontents to escape, without removing them from the said holder. Thusit is seen that a number of flasks F may be handled as a unit, and inthe time normally consumed, heretofore, by the same operations inconnection with one flask. By the spacing and arrangement of theuprights 23, the faucets or stop cocks 13 of the flasks F are heldfixed, and the contents of the flasks may be allowed to escapetherethrough into dishes without changing the positions of the asks ortheir faucets orstop cocks.

In order to provide for the tiltin of the holder so that the contents ofthe asks F may readily flow therefrom when the faucets lates the angleof said base to the horizontal' plane, which angle may be adjusted atwill by means of said set screws.

vIt is to be understood that the present holder may be used in anyconnection Where itis desired to provide a container for a number 0fflasks ortest tubes, it being ,possible to change the details ofconstruction without departing from the spirit and'scope hereof.
